GALVANIC ELEM ENT.

SPECIFICATION forming part of Letters Patent No. 523,892, dated July 31,1894.

Application filed september 2'7, 1893. Serial No. 486,642. (No model.)

To all whom it may concern.-

Be it known that I, ALBRECHT HEIL, watchmaker, of Ober-Strasse,Frankisch Orumbach, in the Empire of Germany, have invented a new anduseful Galvanic Element, of which the following is a specification,reference bein g had therein to the accompanying drawing.

This invention relates to galvanic elements and it has for its object torender the element proof against oxidation of the binding screws,smalland convenient in shape with relatively powerful action, hermeticallyclosed to prevent evaporation of the liquid, cleanly and nice inappearance and easy to make.

The'invention will be described with reference to the accompanyingdrawing, forming part of this specification, representing a verticalsection, wherein- I b is a lead rod or support having at its lower end aprojection b, extending into awooden base or disk 0, its upper end beingpermanently fixed in the hermetically closing cover d and provided witha terminal e. A plate 8 of silver is soldered to the leaden support, andthe conducting support band plate 8 are embedded in a mass of poundedcarbon or and peroxide of manganese in small pieces, inclosed in a linenbag w whose mouth is tied tightly at 11 around the support 1).

F, is a cylindrical diaphragm of felt sur-' rounding the linen bag, andthe zinc Z is bent to cylindrical form around the felt, a vertical slitn being left for access of the liquid to the fe1t, and the exteriorsurface of the zinc is coated with an acid proof covering. The whole iscontained in a glass jar g together with the electrolyte. A tinnedcopper wire conductor h is soldered to the zinc cylinder and passes outof the cell through a slit in the wooden cover d.

Whatl claim, and desire to secure by LettersPatent of the United States,is-

1. A galvanic element consisting of a negative electrode attached to aconducting support made of a base metal, a depolarizing compound inwhich the said electrode is embedded,a bag containing the saiddepolarizing I compound and tightly fitted around the said conductingsupport, a felt diaphragm surrounding the bag and a positive electrodelocated exteriorly of the diaphragm, substantially as specified.

2. A galvanic element consisting of the combination of partshereinbefore specified, viz: a silver electrode attached to a leadsupport sealed through the cover and embedded in a mixture of carbon andperoxide of manganese, inclosed in a'linen bag, a felt cylinder ordiaphragm surrounding the same, and adapted to be saturated with asuitable liquid, and a zinc electrode, substantially as specified.
